About this race

The Chepstow Running Festival 10k takes place entirely within the grounds of Chepstow Racecourse, home of the Welsh Grand National, on the Welsh side of the Severn Estuary. The course covers two laps of a 5km circuit, run on the racecourse's own roads and paths with some short gravel sections rather than on the turf itself. The route is described as scenic and undulating, taking runners around the racecourse grounds with around 182 feet of elevation change over the full distance, giving a fair test without any single severe climb. Because the entire race takes place inside the racecourse, it is free from traffic throughout, with each mile accurately marked and plenty of marshals on hand. Runners finish to a mock chequered flag finish in an iconic Welsh sporting venue, with a lively event village, food and drink, and a themed medal waiting at the end.
